<p>Restored from the archived ChristmasWiki backup. Image references updated where required.</p> <p><b>New page</b></p><div>==P16F688.inc Line 182 Error==<br /> <br /> Some versions of MPLAB have an error on line 182 of the file p16f688.inc. If you encounter the error message:<br /> <br /> Error[111] C:\PROGRAM FILES\MICROCHIP\MPASM SUITE\P16F688.INC 182 : Missing symbol<br /> <br /> then you will need to change the p16f688.inc file.<br /> <br /> Use a text editor (notepad should work just fine) to open the file (making a backup would be a good idea), and remove the extraneous symbol at the beginning of line 182 of the file. Save the file, and you should be on your way.<br /> <br /> ==PIC16F688 programming adaptor for PicKit2==<br /> <br /> It is possible to purchase a PicKit2 programmer from Microchip that does not include a programming socket. In order to use these to program the PIC16F688 that is used with Renard, it is helpful to build a socket.<br /> <br /> Here is an example of a socket adaptor for programming the PIC16F688 (it works with some other PICS as well, such as the PIC12F629, PIC12F675, PIC12F615, etc). It was built using a pin-strip header, a 14-pin socket and a perf board from Radio Shack. Here is the netlist for this adapter (&#039;&#039;&#039;ignore the resistors in the photo below, they were put there for measuring current, and are not needed&#039;&#039;&#039;):<br /> <br /> Pin 1 of Connector (VPP) - Pin 4 of socket (RA3)<br /> <br /> Pin 2 of Connector (VCC) - Pin 1 of socket (Vcc= +5)<br /> <br /> Pin 3 of Connector (GND) - Pin 14 of socket (Vss = 0v)<br /> <br /> Pin 4 of Connector (Data) - Pin 13 of socket (RA0)<br /> <br /> Pin 5 of Connector (CLK) - Pin 12 of socket (RA1)<br /> <br /> Pin 6 of Connector (Aux) - unused<br /> <br /> Added by CP1 : For dummies like me who are new to this.... the pins on the socket go down 1-7, then across to 8 and up to 14. In general pins 1 and 14 are across from one another.
